Application filedNovmber 13, 1922. Serial No. 600,767;

T all born it may concern:

Bait known that I, BISMARCK REYNOLDS, a citizen of the Unlted States, residing at Kansas City, in the county of Jackson and easily applied fastener which can be secured to the top rail of a window sash so thatits 20 effective part may normally be out of operative position, but so arranged that it may be easily thrown into operative position to hold the window sash from being raised by unauthorized persons. The device is so applied that the sash toywhich it. is attached may be held closed or it may be held in any adjusted position so that it cannot be raised beyond the point for which it was set. I

The novel" construction of the invention will be apparent by reference to the following description in connection with the, accompanying drawings, in whichi Fig. 1 is a perspective view of the fastener applied, the inoperative position being shown in dotted lines. a

Fig. 2 is a detail perspective view of the fastener detached, and

Fig. 3 is a detail perspective view of a slightly modified form of fastener;

Referring: now to the drawings by numerals 6f reference 1 designates the vertical rail of a window frame of ordinary construction in which is .slidably secured a sashf2, the sash being balanced by weights on the ends of cords,

there being two cords used in the usual waybut only onedesignated 3 is shown' The fastener as shown consists of a base member 4 having openings 5 and 6 through which fastening devices such as screws .7 and 8 may pass to fasten the base to the top This invention relates to window sash,-

rail 9 01? the sash. Hinged to the base 4 is a tongue 10 having bifurcated ends to provide prongs 11 and l2adapted to straddle the cord 3. Theends of the prongs l1 and 12 may engage the window frame when the tongue 10 is in the position shown in Fig. 1. Therefore, the sash 2 cannot be raised because the ends of the tongue will engage the sash and prevent any upward movement, If it is desired to raise the sash. the tongue will be thrown over into the position shown in dotted lines in Fig. 1. whereupon the sash can be raised and lowered in the usual way. in F 1g. 8 I have shown the tongue ltlas prongs being tipped by caps or tips 13 and .lof rubber or other soft material so that i provided with' the prongs l1 and 12, the

the'window frame will not be marred by the metallic ends-of the prongs. The construction shownin Fig. 3 conforms exactly to narily the'tongue 10'will give the best results if it assumes an angle of about 45 degrees' or even slightly less from" horizontal. It should fold far enough away from the vertical to prevent liability-of slipping when the ends of the prongs 11' and 12 engage the frame. 1. g

What I claim and desire to secure by Letters-Patent, is: a

As an article of manutacture, a sash lock ,comprislngtwosmembers hinged together,

one being a relatively short base member adapted to be positioned on top of the shaft with its free end directed away from the sash cord, the second member being hinged tothe first andconsisting of a still plate having at its free end spaced prongs, the prongs and body portion of the plate being, inthe same plane. i s

In testimony whereof I affix my signature.
